EDITOR’S COMMENTS

Making a splash Here in Cape Town, as we prepare for the rainy season, we turn our attention to a very important, and often under-appreciated, aspect of roofing – waterproofing.

W

e kick off our waterproofing feature with an industry focused Q&A with Paul Koning of the Roofing and Waterproofing Institute (RAWI). This article casts a light on the current state of this industry in South Africa, the challenges that present themselves in this sector, and of course, the importance of education and training in ensuring good quality workmanship that will build on the industry’s reputation.

We also share a checklist for the rainy season from Frederik Nel of Curasure, as well as further insight from the Professional Waterproofers Association (PWASA) whose contribution underpins the importance of quality materials and training in securing this industry’s future in South Africa.

We are delighted to share news from the South African Metal Cladding and Roofing Association (SAMCRA) on Safal Steel’s recent membership, as well as a joint contribution

from the Association’s Executive Director, Dennis White and the Education Director of the Southern African Institute of Steel Construction (SAISC) on the present state of the steel industry and what the future holds for this vital sector.

This issue of SA Roofing has brought to light the fact that there are many smaller operators in the roofing industry that may, for various reasons, be using inferior products and applying them incorrectly. Education is key in so many instances, another important aspect raised here.

With that, we wish you a warm and safe leak-free winter.

Enjoy the read!

SAMCR A NEWS

Safal joins SAMCRA The Southern African Metal Cladding and Roofing Association (SAMCRA) has announced that Safal Steel is the latest blue-chip company to become a SAMCRA member. Other producer mills who are also members of SAMCRA are ArcelorMittal South Africa and BlueScope Steel.

T

he Safal Group, which produces and markets steel roofing products across Eastern and Southern Africa, is the largest steel roofing company in Africa with its combined outputs of 36 operations in 11 African countries. It is the continent’s first producer of Aluminium-Zinc coated steel.

Mosale Raghuram, Safal Steel Business Head, says that SAMCRA has made a real difference to the overall governance of the industry in Southern Africa. “In essence it has become the custodian of the ethics standards of the industry,” says Raghuram. “In this regard SAMCRA has played its part in making our industry a much better place for the end user who is now more protected against fly-by-night suppliers interested only in making a ‘quick buck’ and certainly not interested in the long-term sustainability of the product.”

He adds that Safal is pleased to have become a member of SAMCRA and will do whatever it can to help SAMCRA become even more effective going forward.

SAMCRA director, Dennis White says that the membership of ArcelorMittal, BlueScope Steel, Safal and many other blue-chip companies is an indication of the appreciation the industry has for SAMCRA. “We are proud to have these great companies as members and this motivates us to continue with the work we are doing in the industry,” he says.

This work includes, inter alia, such important activities as the drafting of new standards and of training personnel in the industry in these standards and other important skills.

“We completed the draft of the new standard for cladding (external envelope) late last year,” says White. “This standard not only complies with the requirements of the National Building Regulations but also with other international standards. Subjects covered in the new standard include types of material, durability of coatings, fasteners and ancillary items together with criteria for the design and installation of profiles.

It also includes a comprehensive procedure for the testing of profiles and the presentation of results, which will assist both engineers and specifiers in the selection of cladding profiles,” says White.

The standard, which relates to SANS 10400 part L, will be published after acceptance by the SABS as a national code.

White says that SAMCRA is now assisting with the drafting of a standard in the SANS 2001 series which will replace the largely redundant SABS 1200-HB.

JUNE 2015

Mosale Raghuram, Safal Steel Business Head

In terms of training, SAMCRA workshops for industry sales personnel have been a resounding success with more than 110 people attending the past three workshops. “The training focuses on the technical knowledge required to sell the product effectively and plays a crucial role in the standardisation of product information for all the various products across the board,” says White.

He adds that a number of loss-adjusters have come to SAMCRA for advice when there have been industry problems on which they have to report. “This is an indication that SAMCRA is now becoming recognised as the ombudsman for this industry’s standards,” White says.

Meanwhile since SAMCRA’s founding a little over a year ago it has grown its membership by almost 100%. “We started with nine founding members and today we have 16 members with three new membership applications pending,” says White.

With respect to membership, White says the intention is to include everyone with a stake in the industry, from the producers of coated coil, metal cladding, tiles and associated product manufacturers, to the contractors, professionals, developers, financial institutions and relevant government departments.

A S B E S TO S

Best practice when dealing with asbestos roofs in the built environment At some point as a building owner, a construction professional or a contractor you will be faced with an asbestos-containing roof that is presenting water ingress problems, is required to comply with the latest Energy Efficiency Standards due to additions or simply requires a facelift for aesthetic reasons.

P

rofessionals or contractors encountering asbestos roofs may feel confusion about how to handle asbestoscontaining materials. Some may even avoid asbestos roofs altogether, assuming they will equate to expensive asbestos-removal procedures and red tape. However, asbestos abatement (the process of removing or minimizing asbestos health hazards from a structure) can take many forms, including removal, enclosure or encapsulation and doesn’t need to be as daunting as it seems.

The first step when deciding best practice on how to deal with an asbestos roof is to ascertain whether the material in its current condition is at risk of releasing asbestos fibres. Friable asbestos-containing-materials (ACMs) are considered dangerous or at risk of releasing fibres, whilst non-friable ACMs are considered safe and at no risk of releasing fibres.

• Friable ACM is any material that contains more than one percent asbestos by weight or area, depending on whether it is a bulk or sheet material and can be crumbled, pulverized, or reduced to powder by the pressure of an ordinary human hand.

• Non-friable ACM is any material that contains more than one percent asbestos, but cannot be pulverized under hand pressure.

10

There are further sub-categories of non-friable ACMs with asbestos-cement corrugated roof sheets falling into the lowest risk category. If you are still unsure of the material’s condition, an assessment of the material can be carried out by an authorised asbestos assessment consultant.

The vast majority of asbestos-cement roofs encountered in South Africa are however in a non-friable condition and are at no risk of releasing asbestos fibres. Safer abatement methods, such as enclosure or encapsulation, should be used in these cases.

The average asbestos cement sheet contains no more than about 10% asbestos and the fibres are deeply encapsulated within a cement casing. The inherently strong natural bond between cement and asbestos fibres makes emission of fibres impossible without physical abrasive cutting, abrasive cleaning, impact damage, severe lichen encroachment or fire damage.

Demolition and removal carries a higher risk of releasing fibres whilst disposal has severe environmental consequences. There are numerous documented cases in the UK where asbestos cement roof sheets in excess of 70 years of age are still in a non-friable and safe condition. The township of Soweto was built some 50 years ago using locally manufactured corrugated asbestos cement sheets for roofing.

JUNE 2015

A S B E S TO S

In 2007, the community raised their concerns about the presence of high numbers of council houses that had asbestos roofs in the area. A documented public study was conducted by the National Institute of Occupational Health which showed that there was no evidence of airborne asbestos fibres present in the area due to the asbestos cement roofs. Asbestos fibres were however found in soil samples, but these were attributed to the council’s regular cleaning of these roofs by means of abrasive high pressure water jetting. The contaminated soil samples corresponded with the grey water run-off patterns.

Enclosure of asbestos roofs by means of over-roofing addresses and eliminates all water ingress problems, aesthetics and longterm protection of the ACM. It is imperative, however, that only tested mechanical spacer systems are used that are specifically designed to create a structural interface between the existing roof structure and the new outer roof covering.

This will ensure the structural performance of the roof assembly under loading conditions. These spacer systems are further designed to provide a defined cavity in a variety of depths to facilitate the installation of an insulation blanket in order to comply with current Energy Efficiency Standards.

HEALTH & SAFETY Asbestos-cement roofs should be considered fragile and when any roof work is performed, suitable roof ladders, duckboards or crawling boards should be utilised in accordance with regulation 12 of the General Safety Regulations published by Government notice R1031 of 30 May 1986. Good practice is to install a cargo net over the existing asbestos roof which is, in turn, secured around the perimeter. This sacrificial fall arrest system remains in-situ once the insulation and new outer roof covering have been installed.

ENCAPSULATION Once it has been established that it is safer to enclose or encapsulate the existing asbestos roof in question, the next decision is as to which is the more suitable option.

Encapsulation usually entails spraying the asbestos-containing material with a sealant that will ensure that the fibres are contained within the material. Encapsulation works well when there are no existing water ingress issues, when there is no requirement to upgrade the thermal performance of the existing roof to comply with new energy efficiency standards or where aesthetics are a consideration.

In certain instances where severe neglect and moss growth have caused the immediate outer surface of an asbestos roof sheet to become ‘chalky’ it is recommended that an encapsulation process be applied before further enclosure is carried out. This form of encapsulation is still more economical, less invasive and environmentally friendly than complete demolition and disposal.

JUNE 2015

In accordance with the South African regulations there is no requirement to be registered as an approved asbestos contractor to carry out asbestos roof enclosure. It is however still a requirement that an employer or self-employed person notify the provincial director in writing prior to the commencement of asbestos work and ensure that written procedures are laid down and followed to prevent the release of asbestos dust into the environment. All suitable Health and Occupational Safety precautions should be followed whilst carrying out the work.

There is no requirement to evacuate the tenants of the building during enclosure, but it is recommended from a health and safety perspective to ensure that the vicinity directly below the operation is kept clear in the unlikely event of falling debris.

Spacer systems are traditionally secured through the troughs of the asbestos sheets into the underlying purlin. This process produces very small amounts of dust, which is prevented from entering the building by the underlying purlin and is pulled outwards by the thread of the fastener.

11

A S B E S TO S More advanced spacer systems are supplied in conjunction with H-Series specialised asbestos vacuums with drill cup attachments which capture 100% of the dust produced during the installation process. These vacuums are fitted with an Ulpa Filter for 99.999% efficiency at 0.12 micron. They are ESD safe, meet HSG264 standards of surveying and are fully compliant with BS EN 60335-2-69.

Enclosure of asbestos-cement roofs by means of over-roofing is widely recognised internationally as a safe, cost-effective and non-invasive alternative to removal.

Over-roofing is an environmentally sound way to deal with roof coverings that contain asbestos. The Asbestos Information Centre of the United Kingdom (www.aic.org.uk) states: “Asbestos materials, which are sound, undamaged and not releasing fibres, should not be disturbed. Their condition should be monitored on a regular basis. Removal should only be performed where repair is not possible or the material is likely to be disturbed.”

BENEFITS OF ASBESTOS-ENCLOSURE • Minimises building occupants’ risk and disruption of trade South African legislation stipulates that occupants of a building where asbestos roof sheets are being removed vacate the premises. Leaving the existing roof covering insitu allows the occupant of the building to continue with their day-to-day business operations without costly disruptions to trade. Consequential damage due to inclement weather and falling debris usually associated with conventional re-roofing is eliminated when over-roofing.

12

• Eliminates rising costs associated with removal and disposal of asbestos South African legislation stipulates that the removal and disposal of asbestos may only be carried out by registered asbestos removal contractors. Removal and disposal costs are high due to safety procedures, transportation and disposal costs.

• Labour and time savings Leaving the existing roof covering in place eliminates the removal phase. This in turn reduces the duration of the project, which contributes to significant financial savings.

JUNE 2015

• Improved health and safety The existing asbestos-cement roof sheets remain in place, providing the contractor with a platform to work off. This significantly simplifies the fall protection plan required. The majority of loose asbestos fibres, if any, are present between the side-laps of the existing asbestos-cement roof sheets.

These fibres are only at risk of being released when the roof sheets are lifted and removed. Leaving the existing asbestoscement roof sheets in position eliminates the risk of releasing fibres and exposing the contractor or occupants to contamination.

• Energy Efficiency Over-roofing with the Ashgrid Spacer System, for example, creates an engineered, structurally defined cavity between the old and new roof coverings. When insulated, this cavity dramatically improves the overall energy efficiency of the entire building. With ever-increasing electricity prices in

• Acoustic performance Creation of an insulated cavity dramatically improves the acoustic performance of a roof. Acoustic performance is imperative when an environment conducive to learning, libraries, broadcasting facilities, court houses, etc. is required.

• Environmental benefits Our landfill sites are filling up at a rapid rate. Over-roofing asbestos-cement roofs prevents further deterioration of the product, rendering it inert and safe. Whereas asbestoscement products that are disposed of in landfill sites continue to degrade due to exposure to the elements. This continued uncontrolled deterioration has a severe impact on our already-fragile environment.

• Security Over-roofing incorporates a second layer of roof covering which provides additional security. The majority of commercial break-ins occur through the roof. This additional layer of roof covering provides an extra barrier to deter criminals.

South Africa, energy consumption has become a big concern for most property owners and tenants. Significant financial savings are possible over the life cycle of the new roof covering when insulated appropriately. It is a further requirement under SANS 10400 XA that existing roofs of a building undergoing additions or alterations be upgraded in accordance with the prescribed performance in SANS 10400 XA.

Spotlight on steel in South Africa SA Roofing garners industry insight from key SA steel industry players, Spencer Erling, Education Director of the Southern African Institute of Steel Construction (SAISC) and Dennis White, Executive Director of the Southern African Metal Cladding and Roofing Association (SAMCRA).

Q: Steel suppliers can source material from various quality

mills around the globe, including the local mills. Is there a marked difference between imported product and locally produced steel? If so, what are those differences?

A: Firstly it must be understood that not all foreign mills

produce quality materials suitable for conversion into cladding products that comply with the National Building Regulations (NBRs). In a nutshell, it is possible to procure superior, equal or inferior products, to those manufactured by local mills, from foreign mills. Quality is therefore determined by the individual cladding manufacturer or importer of the cladding products sold into the South African market.

Invariably, mills produce product that complies with the codes/ standards applicable in the country of origin, if a standard exists, or to the mills’ own standards.

14

However, the more reputable mills produce product that complies with recognised international standards, as do our local mills.

We wish to stress that the thickness and quality of the protective coating/s are equally important to the performance of cladding. The steel core provides the strength, whilst the coating provides the weather resistance.

The issue of quality is not confined to steel products and extends to other metals such as aluminium, stainless steel, etc.

In the price-sensitive informal, DIY and emerging contractor sectors, price has become paramount without any regard for structural integrity and durability of the products being foisted on an unsuspecting consumer, or for the Consumer Protection Act (CPA).

JUNE 2015

Q: What attributes or manufacturing capabilities make for a

A: An SABS mark in conformance with a given specification

A: It is a relatively inexpensive entry level business to get into,

the SABS mark?

would be an assurance that a level of quality for that product has been achieved. Unfortunately there is no existing suitable standard for cladding. This matter is currently being addressed by a number of SABS technical committees.

Most reputable local manufacturers require supplier mills to indelibly label input coil, at regular intervals, with the manufacturer’s name, quality of steel, type and thickness of coating/s plus thickness of material.

Q: What standards do imported products have to adhere to, locally and/or in their countries of origin?

A: Large quantities of imported products are being sold in

South Africa with certificates, supplied by the foreign manufacturer and/or importer, claiming the products comply with international standards, yet when tested locally by reliable institutions, the performance of the products falls far short of that required by the relevant international standards. The fastener industry is plagued by this problem The propensity to cheat is rife on both sides of the border.

This aspect is of particular concern to the National Regulator for Compulsory Specifications. Legislation to have products tested for compliance by local accredited institutions will help to alleviate this problem.

Q: How do international trade conditions and regulations impact industry?

A: The international situation is that there is a glut of steel

available, i.e. production is greater than apparent demand and so producers are looking for markets to ‘dump’ their excess products. The weakening of the Rand does, for short periods of time, give some assistance to local producers to be slightly more competitive, but with the weakening of the Rand, producers have associated inflation of their costs. Hence the relatively small and short durations of the weakening Rand impact.

What is clear is that the harbours are battling to cope with the enormous quantities of all imports and finding enough trucks to transport the imports to internal markets. In addition, there is always a layout of capital to fund imports which does help South African producers, because buying from them does not require tying up of capital as imports do (i.e. issue letter of credit with orders).

Q: What challenges does industry face around the supply and/

or transport of local product? How does this trickle down to the end user in terms of supply availability and costs?

A: There are, from time to time, shortages of some steel products in the range produced locally due to planned and unplanned maintenance of facilities. In most cases this is less than a month in time terms, but surely quicker than ordering from foreign suppliers.

JUNE 2015

I N D U S TRY I N S I G HT

Q: How important is it for locally produced product to bear

quality roof sheet producer?

so it is possible for new suppliers to get into the market using second-hand equipment and the like. What is important, especially for sheets that are not pierced with fixing screws, is that materials with the right hardness are used and the rolled shape is accurate, failing which the sheets do not clamp properly to each other and water ingress can become a problem.

Historically there have been such problems, but usually the survivors in the market have overcome these issues and supply a good product. So the expression ‘caveat emptor’ (let the buyer beware) can ensure a good product by making sure producers have a suitable quality control system in place to ensure the right product.

Big companies usually overview the process to ensure that they receive a product that is to the order specification supported by a good set of quality information. This could even involve dimensional checks (shape, profile, thickness, etc.).

There are companies that do specialise in bullnosing and the like which they do on behalf of the profile roller.

Q: What is the outlook for the industry in the short and long term?

A: Sadly, we predict that the tough market conditions will

continue for some time yet – big companies predicting up to three years. So the cladding market, which has held up reasonably well, is not quite as bad as other more general contractors. Government spending is very slow in coming through, if at all, for markets that use roofing.

Q: What other major challenges does industry face at this time? What are potential solutions to these problems?

A: Shortage of skills, occasional erratic supply of materials,

low productivity of South African workforce, poor work ethic of some South African workers, and the South African labour law all play havoc in all local industries. It surely impacts the same way on the cladding industry. ‘Survival strategy’ should be the watchword of all South African companies going forward.

Q: Any closing thoughts?

A: We are really looking forward the publication of SANS

specifications that will come out of the technical committees mentioned above. We hope these will do much to bring industry standards up to a high level, so that we will once again be able to wave our flag proudly and with the assurance of the quality of our home grown products.

WATE R PROO F I N G

Roofing Matters In the first of our new Q&A series that taps into the insight of various roofing industry experts, Roofing and Waterproofing Institute (RAWI) Chairman, Paul Koning talks to SA Roofing about the ins and outs of the South African waterproofing industry.

Photo by Erich Ferdinand

SA ROOFING: The construction industry must comply with detailed legislation within the National Building Regulations, ranging from safety to insulation stipulations. Are there specific regulations for waterproofing manufacturers and/or installers to follow in, for example, SANS 10400?

PAUL KONING: The latest SANS 10400 – Building

Regulations Part L: Roofs (deemed to satisfy regulations) of November 2011 is the latest which includes the section 4.3 on waterproofing.

The Roofing and Waterproofing Institute (RAWI) prides itself on its aims and objectives that include training, education, the upliftment of waterproofing standards and ethics for the benefit of all in the industry and in the end, the client/customer.

18

It is important to select the right waterproofing system for the specific application.

SA ROOFING: Is it important to use only those products bearing the mark of the SABS or Agrément in South Africa?

PAUL KONING: Today, there are very few waterproofing

products that have an SABS mark, if any. Some products carry a South African Agrément Board Certificate, which means that the product has been tested ‘fit for use’ for its intended purpose and for use in South Africa, which is important. Not all types of products have necessarily been tested, but those that have such a certificate should be preferred over the equivalent products that do not have such certificates.

JUNE 2015

that offer membership to manufacturers, suppliers, and applicators of waterproofing materials and systems. These bodies aim to uplift the ethics and standards within the waterproofing industry. What is your view: How important are these associations, and how do you think the industry can benefit from membership?

PAUL KONING: There are various waterproofing

associations and institutes and one hopes that they all have the same aims and objectives. The Roofing and Waterproofing Institute (RAWI) prides itself on its aims and ojectives that include training, education and upliftment of standards, ethics and people for the benefit of all in the industry and in the end, the client/customer. The Waterproofing Association Gauteng (WAG) is also very active in promoting and trying to uplift standards and ethics in the industry. I believe these associations and institutes are important and need as much acceptance and encouragement as possible from specifiers and clients/ customers.

SA ROOFING: What are some of the biggest challenges the waterproofing industry faces in our country today?

Training is very important and RAWI is doing as much as possible in this regard with the CETA recognised and approved HP Plum Training Academy, which is also known as the RAWI Training Academy, which offers the only CETA approved waterproofer training courses and certificates.

The other very important challenge is to ensure that the main building contractor provides quality work to the standards required for good waterproofing. Unfortunately, the standard of builders' work is far from acceptable in many cases. The other challenge is to be able to get experienced and knowledgeable management, as qualified supervision of the waterproofing works on the site is lacking in many cases. Too often, workmen are dropped off at the site and left to their own devices without the correct and experienced supervision.

WATE R PROO F I N G

SA ROOFING: There are regional waterproofing institutes

SA ROOFING: How do you think these challenges should be addressed and by whom?

PAUL KONING: Everybody involved in the waterproofing

industry, from manufacturers to contractors should make it their responsibility to train and get involved in such CETA approved training academies like the HP Plum Training Academy/RAWI Training Academy.

PAUL KONING: A great challenge facing the local

waterproofing industry today is a lack of understanding by the industry and end user of the importance of good waterproofing.

The lack of regulated standards also poses a challenge.

However, all National Regulations are slowly being improved and these should be followed.

Continued on page 20.

WE CREATE ROOFS Established 1956

Your home is your castle and if you want your house to really stand out from the rest, we are the roofing specialists for you. We have been in the roofing business since 1956 and realize how important it is to have a good looking home that is also weatherproof and long lasting.

When choosing a roof covering, certain elements, like the roof pitch, architectural appearance, economy, insulation properties and atmospheric and chemical influences should be considered.

The main aspects of a roof is to rainproof (not waterproof) a structure, stand up to any type of weather conditions such as storms and gales without showing great signs of change, to be light in weight and provide some degree of protection against fire.

We have designed, patented and installed a number of roofing products and accessories, such as Alpklip, Stormkap, Perer de Luxe, and of course our ever popular Peterlo. Minor but important attention to the details of hips, ridges, valleys, verges, abutments and flashings to chimneys have been perfected over the years.

The first Peterlo roof – patented by Master Roofer, Peter Plum – was installed in 1960 in Claremont and is still intact. The new Peterlo Stormkap patent incorporates the proven Peterlo system as well as the innovative Stormkap system to treble the lifespan of a roof.

SA ROOFING: What are the main differences between

waterproofing in exposed situations such as concrete, timberboarded or insulated roofs versus waterproofing in buried or covered situations like roof gardens, parking decks or underneath tiles?

PAUL KONING: The application of an exposed or covered

waterproofing system is up to the design of the building. It is important to select the right waterproofing system for the specific application. The life expectancy of most waterproofing systems will be less in exposed situations as they will oxidize quicker.

In exposed situations, maintenance, such as repainting is important to help prolong the life expectancy. With the introduction of SANS 204 and SANS 10400 XA, the energy efficiency in building has become regulated and flat roofs have to be insulated to either prevent heat loss or heat gain, or both, depending on the given region. Therefore, exposed roofs are often covered with an insulation material and stone ballast protecting the membrane from premature deterioration. In covered situations, whether under screed and tiles or in a roof garden, no maintenance is possible.

SA ROOFING: How important is it to use a South African manufactured waterproofing product versus an imported product?

PAUL KONING: It is always a good idea to buy South

African products, for obvious reasons, but there are also some very good and competitive imported products available.

It is always important, however, that if one is going to buy imported waterproofing products to make sure the local company is an established and longstanding supplier of waterproofing products and has a qualified and experienced after sales service, so that if anything does go wrong with the product, your recourse is in South Africa and not overseas in the country of manufacture. If you are buying an imported waterproofing product, make sure it has a history of being used in South Africa for at least 10 to 15 years which can be referenced.

SA ROOFING: What qualities would a specifier look for in a quality waterproofing product?

PAUL KONING: Always look at the size, history, expertise

and knowledge of the manufacturer/supplier and the number of years they have been manufacturing and/or supplying waterproofing systems. Look at the integrity, expertise, financial stability and number of years the waterproofing contractor has been in business. The cheapest in not always the best and as the old saying goes, “You get what you pay for.”

SA ROOFING: What sort of guarantee should be offered

by the manufacturer of a waterproofing product? How about a contractor/installer’s guarantee on workmanship?

PAUL KONING: Normally the waterproofing system/ product will carry a 10-year warranty/guarantee on the product. The specialist waterproofing contractor will give a 10-year workmanship guarantee, but this is not an unconditional guarantee that you will not have any leaks. Firstly, the manufacturer warrants against the product being faulty, and the specialist contractor guarantees that he has laid the materials in strict accordance with the manufacturer’s

20

instructions. There are conditions to these warranties and guarantees. Do not accept a quotation on the guarantee.

SA ROOFING: What sort of training is required to become

a waterproofing installer/contractor? Is there a training academy, or is it ‘on-the-job’ experience that counts? Or, can anyone go to the local hardware store and buy a product and apply it to that leaky roof?

PAUL KONING: Unfortunately, too many people out there think it is easy to set up a waterproofing company. This is not the case, as there is much more to waterproofing than that. I do not believe that waterproofing systems should be sold in hardware stores. Many waterproofing systems may appear to be easy to apply, but they are not easy to apply correctly. Get an experienced waterproofing contractor to do the job, even if it costs more initially. In the end it will be very cost effective.

SA ROOFING: Could you elaborate on the various waterproofing materials available to the market today?

PAUL KONING: All waterproofing materials and systems

have their place and it is important to ensure the waterproofing system used is fit for purpose. There are many systems that will be fit for the same purpose and some that will definitely not be. Do your research on the internet and do not necessarily take what a product salesman says as ‘right.’ Be sure to run your information by as many reliable sources as possible. You do not want to have to re-waterproof your roof a few years later because you were sold the wrong product for the application. There are some good independent consultants that have years of expertise and knowledge that will advise on suitable systems for certain situations without having to specifically name manufacturers.

SA ROOFING: How would you describe the outlook for the waterproofing industry in the foreseeable future?

PAUL KONING: There are two sides to the waterproofing industry: the new works and the re-waterproofing works. The amount of new waterproofing works is obviously subject to the state of the economy. The re-waterproofing side will always be there, as buildings have to be re-waterproofed at some stage in their life. Whether the building owner wants to do a proper job or just patch up the problem is another issue altogether. However, it is up to the specialist contractor to explain the pitfalls inherent in doing such a ‘patch’ job.

SA ROOFING: Any final thoughts about waterproofing for SA Roofing readers?

PAUL KONING: Waterproofing is an important element of a building and should not be taken lightly. The potential consequential damages, costs and inconvenience of a leaking roof are very serious. There are three very important aspects of good waterproofing – training, education and top supervision of the job.

Human settlements meeting energy targets The enhancements to the norms and standards for the construction of stand-alone residential dwellings, engineering services and adjustment of the housing subsidy quantum, especially in terms of ceilings and insulation, have improved the quality of housing.

T

hese parameters are based on the requirements of the 2011 revised National Building Regulations, SANS 10400 XA - Energy Usage in Buildings. These measures have been put in place to improve the thermal performance of the dwellings.

The ceiling and insulation component of the building has the greatest potential to reduce the thermal loads by up to 31%, leading to direct cost saving and reduction of emissions. This makes the Department of Human Settlements one of the key players in helping South Africa reduce emissions by 34% below ‘business as usual’ levels by 2020 and by 42% by 2025.

The average heat load on a 40m2 home is 3 401 kWh per annum at a cost of R 4 081.87 and the emissions at 3 264 kgCO2 per annum.

HOW ISOVER GLASS WOOL INSULATION HELPS US SAVE 6 TONS OF CO2 EVERY YEAR Isover converts discarded waste glass by industry and households into a valuable raw material. Isover glass wool consists of about 80 % of recycled waste glass and the other ingredients, such as quartz sand, soda ash and limestone, are virtually inexhaustible resources. This does not only sound, but definitely is ecologically sustainable in many ways. The use of glass wool does not only help us meet the Kyoto target but also realize energy efficient living all around the globe.

Just consider: The production of 1 ton of glass wool releases about 0.8 tons of CO2 . The annual CO2 saving that can be realized by building using glasswool amounts to as much as 6 tons. Assuming a useful life of 50 years, we can thus save up to 300 tons of CO2 – 375 times as much as the CO2 emission caused by production.

Choosing the correct insulation to use in your roofing projects depends on various factors such as, climatic zone, R-value, combustibility of the product and performance.

ENERGY EFFICIENCY LEGISLATION FOR NEW BUILDINGS (NBR-XA) The National Building Regulation (NBR) was updated in November 2011 to include Part X, which addresses environmental sustainability and Part XA which establishes requirements for energy efficiency in new buildings and renovations (which require plans). The application of this new legislation is good news for the environment and will help you save electricity.

FEEL THE REAL DIFFERENCE WITH INSULATION THAT MEETS THE REQUIREMENTS Buildings typically account for 40% of all energy consumed in countries and by insulating with Glasswool it is possible to significantly improve the energy efficiency and comfort of buildings. Isover`s insulation can save 100 times the energy consumed and CO2 emitted in their manufacture, transport and disposal.

Glasswool is made from a combination of naturally occurring silica sand, fluxing agents and up to 80% recycled glass. Glasswool has Zero Ozone Depleting Potential (ODP) and no CFC`s or HCFC`s are produced in the production process. Glasswool can be compressed by a factor of up to 5 which saves on storage and reduces transport costs.

CEILING INSULATION A typical un-insulated home loses and gains up to 35% of its energy through the ceiling and this can be dramatically reduced by installing insulation of the correct thickness.

Think Pink Aerolite is Isover’s thermal and acoustic ceiling insulation solution that reduces the amount of energy required to maintain a comfortable living environment, offering a payback in less than 2 years with continued savings thereafter.

Isover Insulation 130 is a non-combustible Glasswool blanket that has been specifically developed to meet the Department of Human Settlements ceiling insulation requirements for 40m2 housing developments became effective in April 2014.

Our insulation is environmentally friendly, non-combustible, offers excellent sound absorption properties and is easy to install in your home.

Feel the real difference with Aerolite or Isover Insulation keeping you warm in winter and cool in summer.

Looking back and moving forward:

Industrial Action in SA It has been nearly a year since the Metal and Engineering Industries Bargaining Council (MEIBC) strike of July 2014. After extended negotiations, unions and employers’ organizations reached an agreement governing the metal sector up until 30th June 2017.

Photo credit: Richard Rutter

Does this mean that employers should sit back and only start reacting to strike season come June 2017?

For example, the Gautrain Bus Operation’s ‘go-slow’ during May 2015 affected commuters, who probably arrived late for work, impacting on corporate productivity.

The answer is no. Employers and individuals are affected by industrial action more often than we may think, whether directly or indirectly.

26

JUNE 2015

South Africa is known for its violent strikes, but not all strikes are violent. We find that employers give in to employees’ demands as they are fearful things may turn violent, and because a strike could lead to grave financial losses and, in more extreme cases, even closure.

One can therefore never really prepare an employer for a strike. A strike adversely affects the employer and employee; the employer’s business is disrupted to a point where it cannot operate effectively and employees are usually not remunerated for that period.

Once an employer is faced with industrial action the employer must establish whether it is a protected or an unprotected strike. Employers should remember that a strike has a specific definition and if the situation does not conform to the elements of a strike, it cannot be dealt with as a strike. A strike is also protected when it complies with section 64 of the Labour Relations Act. Ideally, a protected strike is pre-empted by a certificate issued by a commissioner of the CCMA or Bargaining Council. The employees and/or their trade union will give the employer at least 48 hours’ notice of their intention to embark on the strike. The purpose of this notice period is to allow an employer to prepare for the industrial action.

Employers should anticipate the worst case scenario and prepare accordingly. The best advice to give employers facing industrial action is to have proper contingency plans in place.

If an employer anticipates that the strike could get violent, it is advisable to get extra security on the premises, if possible. A change in the operating hours is another solution as we find that employees strike during working hours. This, however, will require permission from the employees who are willing to work during the strike. Employers should conclude picketing rules with the employees and/or trade union as quickly as possible. Picketing rules are designed to regulate how and where employees should strike. Employers are normally allowed to have scab labour come in and do the work (if they can enter safely), unless it is excluded in an agreement.

Employers should also keep in mind that employees may not be dismissed when participating in a protected strike. This does not indemnify employees to commit any other misconduct during the strike. Employees are at all times bound by the employer’s disciplinary code.

There are various possible solutions for employers facing industrial action, but it comes at a price and there is no guarantee that it will be successful. It is highly recommendable that employers seek professional help during a strike, as they may face having to compensate striking employees.

Industrial action is a tool to resolve issues between employers and employees. It is debatable whether it is an effective tool, but in the absence of proper alternatives, we have to deal with industrial action as and when it happens.

SA Roofing asks: What is EPDM? Waterbrothers’ CEO, Robert Brooker extrapolates…

SA ROOFING: What is EPDM? What is its composition on a molecular level?

ROBERT BROOKER: EPDM stands for Ethylene

Propylene Diene Terpolymer, which is a synthetic rubber.

The Firestone EPDM base polymer has a saturated backbone carbon chain with pendant unsaturated rings to allow for cross-lining. The backbone carbon chain structure is made synthetically by combining Ethylene and Propylene, which creates a long chain structure, and controlled amounts of Diene are added during polymerisation.

SA ROOFING: How do these micro-properties make it effective for use as a waterproofing medium?

ROBERT BROOKER: Due to the absence of double

bonds in the backbone of the material, it boasts excellent heat-, UV- and ozone-resistance. On the other hand, natural rubber contains a double bond every four carbon atoms and is therefore more vulnerable to cracking after extended exposure to the sun. For this reason, when EPDM polymer is used to produce Firestone EPDM waterproofing membrane, the final product will carry all the abovementioned benefits, as well as those associated with additional fillers used.

SA ROOFING: How can EPDM contribute to a building’s overall energy efficiency?

ROBERT BROOKER: While EPDM’s potential

contribution to a building’s overall energy efficiency is not directly related to the waterproofing membrane, it does contribute to this factor in the line of the insulation system.

By having a good waterproofing system, the thermal properties of insulation will be improved. Employing the use of a good quality product with an extended lifespan (such as Firestone RubberGard EPDM’s of more than 50 years), it can potentially have a low carbon footprint.

SA ROOFING: Does EPDM need to be maintained, and to what extent?

ROBERT BROOKER: As with any system the roof should be cleared of accumulated dust and debris, and scuppers and drains should be checked at least three times a year. No maintenance is required on the EPDM itself.

WATE R PROO F I N G

SA ROOFING: What are some of the advantages of offering EPDM to the South African market?

ROBERT BROOKER: In terms of new business opportunities and using EPDM, companies can gain and solidify their reputation of reliability, ensuring repeat business. The world market for EPDM in this application is huge and the whole African market is new and available to the companies involved at this early stage.

The Firestone EPDM system is a clean system requiring no heat or flame and minimal hand tools. Installation crews are small, generally 2 to 4, depending on the site.

Large sheets also mean that a large work area can be temporarily waterproofed in the case of frequent Highveld thunder showers which only interrupt work for a very short time, enabling crews to continue working within a short time after a shower, making daily production rates high.

SA ROOFING: What does the future look like for EPDM in the SA waterproofing industry?

ROBERT BROOKER: With its wide range of

applications, exceptional resistance to environmental degradation and service life far beyond any other product, the future of Firestone EPDM in both the lining and roofing aspects of the South African waterproofing industry is assured.

Contractors and suppliers now have a multi-use product, available in large single sheets, and application systems geared towards offering a supremely reliable solution to their client base, ensuring business growth into a new and ready market.

applied to several new projects a.b.e. Construction Chemicals’ VIP Polyurea coating has been applied as lining for several new concrete and steel surfaces throughout South Africa.

a.b.e.’s VIP Polyurea Quick Spray Industrial coating was applied for waterproofing and corrosion protection in these galvanised tanks for the creation of biofuel in Bapsfontein. a.b.e., which is part of the Chryso Southern Africa Group, holds an exclusive agreement with VIP (Voelkel Industrie Produkte) in Germany for the local sale and distribution of the German company’s respected range of protective coatings and joint fillers. Produced in Munich, VIP Polyurea coatings have been internationally hailed as a ‘new revolution in coating technology’ and have set new benchmarks in terms of durability, protection, ease of application, and turnaround times.

The product reacts within seconds and once cured, leaves a flexible, durable and rough surface. It is suitable as a protective coating for virtually any surface including concrete, steel, wood, polystyrene, fibre glass, and plastic. The coating is applied using high pressure, heated plural component spray equipment and can be applied at any thickness and in various colours,” Abendroth stated.

Noel Abendroth, a.b.e. Polyurea Performance Coatings Division Manager, said VIP Polyurea Quick Spray Industrial coating was recently applied to:

For the new water park at The Kingdom, a.b.e supplied the coating in a blue colour to applicators, Diamond Linings, which has a fully equipped mobile unit and extensive polyurea experience in the waterproofing, mining, marine, civil, and flooring sectors. A total surface area of about 800 square metres was coated. The completed water park, already in operation, was developed by Rocky Waters, Durban-based specialists in customised water parks and slides, garden features and ponds, as well as rock pools. VIP Polyurea Quick Spray Industrial has also been chosen as lining for two further water parks to be developed in North West Province by Rocky Waters.

VIP Polyurea Quick Spray Industrial was also applied to line new silos designed by Assentoft Silo, Danish specialist manufacturers of silos and tanks for farming and industrial purposes. The silos were built by Bosch Projects at Boskop, near Bapsfontein. “For this project, a.b.e. again supplied the Polyurea product, this time in a grey colour, to Diamond Linings. The silos are used for the conversion of cattle manure and waste foodstuff into biofuels. At the same venue, Diamond Linings applied VIP Polyurea Quick Spray to seal the seams of galvanised metal tanks that contain highconcentrate chemicals. A total of about 400 square metres of the coating was required,” Abendroth said.

VIP Polyurea Quick Spray Industrial was applied by a.b.e. approved Cape Town applicator, Thermoseal, to about 1 000 square metres of concrete passages at the Ashburn residential apartment block in Claremont, Cape Town. “The coating, specified as part of the refurbishment of the six-storey apartment block, not only protects the concrete surfaces but also ensures that the walkways, leading to the front door of the various flats, are not slippery,” he explained.

Finally, VIP Polyurea Quick Spray Industrial was supplied to Hindle Mason Projects, Randburgbased concrete repair and rehabilitation specialists, to replace the rubber linings and provide chemical and abrasion resistance to 18 metre diameter water retaining concrete launder tanks, and 24 metre diameter steel clarifier tanks, at the gas production plant at Secunda.

Preparing for rainy seasons Important areas to check Article by Frederik Nel of Curasure

T

he importance of preventative maintenance and knowing your building, its shortfalls and weaknesses cannot be underestimated. Good life cycle costing and a workable maintenance plan are the only cure for those maintenance headaches. Communal living has taken off in our country, with all the good and bad that comes with it. Generally speaking, trustees and members face a shortage of technical knowledge regarding the major maintenance and upkeep of their complexes.

Make sure that cracked tiles, ridge cappings and general flashing detail are in good order. For flat roofs, ensure that general waterproofing, counter-flashing and outlets are waterproofed and well maintained.

The cost of maintenance and general decline in industry standards makes for loaded responsibilities and consequences when it comes to tackling that dreaded maintenance overhaul of your complex. Various systems in the marketplace exist that will assist you in gathering the correct information prior to refurbishment. Make use of these services and technical knowhow to benefit the outcome of your next project.

As a precautionary measure prior to rainy season it is recommended that the trustees perform a site inspection to list action items that should be completed to prevent damage.

QUICK REFERENCE CHECKLIST:

Repair and maintain gutters and downpipes and ensure good flow of water.

1. ROOFS (PITCHED, TILED, FLAT OR WATERPROOFED)

3. PARAPETS

Depending on the style of roof design and waterproofing, the items will vary.

10. CARPORTS Ensure that shade-netting on carports is tightened and in good serviceable condition.

4. SKYLIGHTS & FITTINGS Seal and secure skylights and fittings on roofs.

5. BALCONIES, TILED AND WATERPROOFED AREAS Ensure that tiled and waterproofed areas are correctly waterproofed and that outlets are waterproofed correctly, open and sufficient.

6. WINDOWS & DOORS Inspect and reinstate failed sealing of doors and windows.

(Install weather strips if required). Include windowsills in inspection.

11. BUDGETS Consult your budget and ensure that sufficient funds are allocated for preventative and interim maintenance prior to rainy seasons or major projects.

It is important to ensure that maintenance schedules and budgets are fully prepared and implemented. An annual inspection and review of the planned maintenance and budget is not only necessary to identify urgent items, but is crucial to ensure accurate reporting and management of all maintenance items.

Prevention is always better than cure.

Quality materials & training key to waterproofing industry’s future Ed Scott-Turner of the Professional Waterproofing Association (PWASA) shares his insight into the current state of the South African waterproofing industry

aterproofing, as easy as it may sound, is a specialist trade and experience, expertise and identifying quality materials are key to the success of any waterproofing application. Various associations, like the Professional Waterproofing Association (PWASA), the Waterproofing Federation of SA (WFSA) and the Master Builders Association (MBA) among others promote high standards in the industry.

MATERIAL USAGE In terms of available waterproofing materials, quality ranges from very good local and imported products, mainly from Italy, to very cheap imports. For the most part, the selection of materials on a given project is made by the architect or engineer, who, in most cases, will use high quality, tried-andtested products.

38

However, many smaller and medium-sized waterproofing contractors who operate in both the domestic and commercial sectors are not under management of property owner or managing agents who dictate product usage. During tougher financial times, these contractors may revert to using cheaper products on the market, so as to save on costs, an unfortunate consequence of which is that some cheaper, inferior products creep into the market.

All waterproofing systems have their place and there is no one product that will solve all waterproofing requirements. It is best to select a reputable waterproofing company or two, who will offer a range of products to successfully waterproof the given structure, and sound, honest advice.

JUNE 2015

QUALITY WORKMANSHIP The quality of workmanship in the waterproofing sector has deteriorated somewhat over the years, mostly due to small, inexperienced operators using inferior products, incorrect application and product selection for the job at hand. This has proven problematic not only for the ethical players in the industry whose reputations are at risk of being tarnished, but also for the specifier and end user.

WESTERN CAPE & EASTERN CAPE www.aspectwp.co.za

There is no formal ‘trade’ for ‘waterproofer,’ like there is for plumbers and electricians, who, in years gone by, had to complete a 5-year apprenticeship and a trade test. This practice ended many years ago and many sectors of the construction industry are severely lacking in skilled people.

With a lack of formalized industry education and training, the PWASA constantly carries out in-house training by the PWASA's members, which it has found to be the best way to maintain industry standards. Some material suppliers also offer basic training courses.

Not just for roofing Butyl Tape, a well-respected adhesive sealant tape brand in the roofing industry, also seals against moisture, dust, weather, fumes and insects

B

utyl tape is a self-bonding, pliable, sticky and flexible adhesive sealing tape that adheres to all metals, plastic, glass, wood, cement, brick, polycarbonate, ceramic, melamine, granite, fibre glass, tar, Bakelite and most porous surfaces. Butyl tape offers instant watertight bonds for optimum sealing and comes in many sizes and thicknesses to serve any application.

“Although we are willing to divulge the raw materials used to make our product (under special circumstances), the process and mixture must at all times be confidential. No other company or entity manufactures our product to the exact same formula or specifications. It is this uniqueness that has guaranteed the success of our product and, the fact that we have not had a quality complaint in 34 years,� says Kenneth Atkinson, Butyl Seal Managing Director.

Butyl Tape is chemically inert, and so will resist oxidation, remain permanently elastic, resistant to cracking, and will not degrade under UV light. (Butyl tape was tested for over 9 000 hours in a UV cabinet without degradation).

Butyl Seal products are noted in field performance and in laboratory tests for permanent flexibility, outstanding age resistance and resistance to hardening. On the other hand, sealants based on, or containing substantial amounts of unsaturated oils, resins, polymers and bitumen, perform well initially, but will oxidize in time and cure or harden for a stiff or brittle end result. On the other hand, sealants not based on Polyisobutylene and butyl rubber will, under the influence of heat, vibration, oxygen and UV radiation, degrade within a comparatively short period of time. South Africa has the highest incidence of UV radiation in the world (Vereeniging).

Although Butyl Seal manufactures a product that has common elements in its formula which categorises it as a butyl based product, the formulation used is solely unique to the company.

40

JUNE 2015

Butyl Tape is chemical-, weather- and age-resistant, and is highly resistant to acids, alkalis and salts. It is also highly resistant mould, mildew, rodents and insects.

The tape is easy to use by simply sticking it to a clean surface and peeling off the quick release paper. Once the tape is positioned, and the quick release paper is removed the two panels or sheets are pressed together with adhesion that strengthens dramatically over time and with warm weather.

SABS Mark for Mapei admixtures Mapei South Africa is proud to announce that its Concrete Admixture product line has recently been awarded the SABS Mark. The SABS certification covers the market-leading range of liquid admixtures for concrete, mortar and grouts that the company manufactures locally. “This is a particularly noteworthy accolade as Mapei South Africa is the first admixture producer in South Africa authorised to display the Mark,” says Mapei South Africa’s General Manager Commercial, Antony Offenberg.

T

he SABS Mark is the highly visible expression of the SABS Product Certification Scheme aimed at providing the consumer with third party guarantees that the quality and reliability of the approved product will be fit for the designated purpose and meet the appropriate standard.

In the past we have supplied our concrete admixtures to a number of notable projects, and the Dynamon brand is now widely recognised. Now, not only can the performance of the products speak for themselves, but the specifier and user of the products can now be assured that the product is manufactured and performs to the South African National Standards.

JUNE 2015

Mapei admixtures were used at the 102 Rivonia Road project.

Through this initiative, Mapei introduces the local concrete and construction market to the international best practices in specification and performance of the correct admixture for the application at hand. It also displays the commitment from Mapei that the product supplied will not only perform against the required standards set by the SANS specification, but that the customer will be guaranteed the product performance that was promised, on a consistent basis.

Mapei South Africa continues to introduce the local construction industry to the benefits of the advanced Mapei building technology additives, sealants, adhesives and concrete performance chemicals.

Mapei’s range of products and solutions cover industrial, commercial and residential applications, from the smallest DIY jobs to the needs of major project sites.

With a proud 77-year history, Mapei is today the world leader in the production of adhesives, chemical products and solutions for building, from facilities operating in over 31 countries on five continents. The key pillars of the company’s success have been its investment in research to drive innovation, the development of a comprehensive product range that provides solutions for virtually all building needs, and the focus on producing eco-sustainable products that are certified by leading environmental authorities around the world.

LSFB

Now it’s Burger King that opts for Light Steel Frame Building Many well-known fast food franchisors have seen the light in terms of building with the light steel frame building (LSFB) method. The latest is the Burger King chain, which has used the method for its restaurant in Norwood in the northern suburbs of Johannesburg.

The entire turnkey project of the Norwood Burger King took an incredibly short 12 weeks to complete.

T

he restaurant was designed in-house by Burger King with the construction and civils given to the Silverline Group (SG).

“On top of this, the construction period required is significantly less than with traditional building methods, allowing the franchise to be trading that much quicker,” Van Zyl says.

“This was a turnkey project for us,” says Charl van Zyl, CEO of Silverline Group. “We did the civil work, building construction and all finishes and even fenced the building.”

John Barnard, Southern African Light Steel Frame Building Association (SASFA) director, says LSFB is definitely much more energy efficient than more traditional construction methods – both with regard to the ‘embodied energy’ of the materials and components, as well as ‘operational energy’ relating to heating and cooling of the building over its design life.

Van Zyl adds that the fast-food chains are using LSFB because they support sustainable building methods as far as design, energy efficiency and the optimal use of natural light are concerned and because, by using LSFB, material wastage can be reduced by up to 30%, transport costs by 80% and the carbon footprint significantly reduced.

JUNE 2015

LSFB

“A recent research project carried out by the CSIR indicated that a light steel frame building will require less than half of the energy needed to heat and cool a masonry residential building to comfortable internal temperatures,” Barnard says.

Speed of construction is especially important to Burger King, as they are new players in the fast food market in South Africa and they are currently planning to expand their South African footprint. In the case of the Norwood building, the entire turnkey project took an incredibly short 12 weeks to complete.

The Burger King Norwood has total floor area of 300m² and both the internal and external walls were built using light steel frame. For external cladding, the Silverline Group used OSB board, protected by a vapour permeable membrane with mesh and stucco plaster providing the durable external finish.

Glasswool insulation is installed in the wall cavities, with firerated gypsum board used on the inside to achieve a perfect finish. “Insulation achieved on external walls on this building was R = 3.69, compared with 0.28 for brick and mortar,” explains Gerrit Burger, Silverline Franchisee.

JUNE 2015

He adds that the building was plastered to achieve the required Burger King external ‘look’, as specified in the USA. “One of our challenges was to get the right type of brick appearance for the bottom part of the building. These are not real bricks although they look like the real thing. Our solution was to customise the brick cladding and to clad it directly onto our plastered walls,” he says.

A MiTek Ultra Span roof was designed by SG Engineering to enable a reduction in heavy steel columns and baseplates due to its longer span capability and the additional strength of the MiTek Light steel frame trusses. “The extension of the facades would have been very difficult and expensive to do in masonry or concrete, and light steel frame was the obvious choice in these circumstances,” he says.

Burger says that there were very few hitches on this project: “Burger King’s designs are perfect for LSFB.” Is Burger King happy with the result? Well, the proof of the pudding is in the fact that the Silverline Group is already on site in Brackenfell building the next Burger King outlet using LSFB!

B -BBEE

B-BBEE: Not just a number The Black Economic Empowerment industry (herein referred to as BEE) has attracted considerable attention over the last couple of months.

Some people are not entirely sure about the scope of recent changes and the effect these mandates may have on their business. To address this, a good starting point is a recap of what BEE is all about and the reason for its existence in South Africa.

Article by Robin Matthews, Managing Director of Invasset Advisory.

RIGHTING THE WRONGS OF THE PAST

CALL FOR CHANGE

BEE is a policy introduced by the post-1994 government to address injustices of the past, by giving previously disadvantaged groups of South African citizens (Black Africans, Coloureds, Indians and some Chinese) economic opportunities previously not available to them. It includes measures such as Ownership, Management and Control, Employment Equity, Skills Development, Preferential Procurement, Enterprise Development and Socio-Economic Development. The Apartheid regime promoted minority white rule and, as such, the majority was not actively encouraged to be part of the mainstream economy. The introduction of this legislation aimed to correct the imbalances of the past, notwithstanding its own set of challenges.

BEE started as early as Thabo Mbeki’s time of being vice president. By then, the legislation had already been researched, and the BEE act of 20031 was subsequently promulgated. The first Codes of Good Practice were gazetted shortly thereafter.

At that stage, however, BEE was not yet a company requirement.

In fact, the majority of the economy was not even aware of it.

(It must be noted that even today, it is not a statutory requirement for a company to be BEE verified, but it has become an economical imperative.)

SIZE OF COMPANY (TURNOVER PER ANNUM) SCORECARD TYPE

Exempted Micro Enterprise (EME)

46

2007 CODES

Less than R5m

2013 CODES

The Codes focused mainly on the implementation of direct empowerment elements in terms of Ownership (equity) and Management & Control (control) in the hands of black 2 people.

This did not actually accomplish the goal of BEE, as this was a very narrow-based approach that did not contribute to the wider economy. Due to this, a more refined and ‘broad-based’ approach was adopted and gazetted on 09 February 2007, titled the Broad-Based Black Economic Empowerment Codes of Good Practice (herein referred to as B-BBEE). The Amended Codes of Good practice, promulgated on 11 October 2013, was implemented on 01 May 2015. This is the legislation that has attracted considerable attention in recent weeks, and understandably so, considering that the goalposts of some elements have shifted rather drastically from the 2007 Code specifications.

THE 2013 SCORECARD STILL SHARES THE SAME THREE SCORECARD TYPES WITH THE 2007 CRITERIA. HEREWITH THE DIFFERENCE BETWEEN THEM:

EVALUATION CRITERIA

Less than R10m

• Automatic a level four Contributor • Level 1 if 100% black owned • Level 2 if 51% black owned • Level 1 if 100% black owned • Level 2 if 51% black owned • Less than 51% black ownership, entity has to be evaluated on all 5 elements on 2013 codes, or 4 out of 7 for 2007 codes

Qualifying Small Enterprise

R5m – R35m

R10m – R50m

Large Enterprise

More than R35m

More than R50m

Has to be evaluated on all elements irrespective of black ownership

JUNE 2015

Initially there were seven elements. Elements all need to be independently verified to achieve a certain level. The level is then coupled to a ‘BEE recognition level,’ which in turn depicts the amount of ‘Rand value’ your customer can claim by doing business with you based on your B-BBEE certificate obtained.

This is measured under the Preferential Procurement element, which is seen as the driving force of B-BBEE. The following table compares the 2007 Codes to the 2013 Codes, depicting the different levels and their respective ‘BEE recognition levels.’ It also shows the increase in thresholds from the 2007 codes to the 2013 codes.

B-BBEE STATUS

>=40 but <45

Level Eight

>=40 but <55

>=30 but <40

Non Compliant

0%

Practical example: If you purchased R1 000 000 worth of goods from a supplier with a level four rating, you can claim R1 000 000 (R1 000 000 at 100% = R1 000 000) as B-BBEE spend under your Preferential Procurement element. So, purchasing from suppliers with high BEE certificates means you will achieve your target easier than when purchasing from suppliers with low BEE certificates.

The bottom line is: The better your level, the better for your customers, and the better chance of your getting more business. It can give you a competitive advantage.

THE FOLLOWING IS A COMPARISON BETWEEN THE 2007 AND THE 2013 CODES: 2007 CODES

2013 CODES

THE 2007 CODES COMPRISED OF 7 ELEMENTS:

B -BBEE

THEN AND NOW

1. Ownership: Black ownership or shareholding of the company 2. Management & Control: Strategic decision makers as well as black board members (i.e. Top Managers and Board of Directors) 3. Employment Equity: Black line management that are permanently employed 4. Skills Development: Training provided to your black employees 5. Preferential Procurement: Goods or services purchased from an entity with a valid B-BBEE certificate – this is the driving force behind B-BBEE 6. Enterprise Development: Black owned (more than 50% black owned) entity that you have assisted for further development 7. Socio-Economic Development: Contributions made towards black beneficiaries (i.e. education, healthcare, programmes aimed at sport development, arts and culture, etc.)

THE 2013 CODES HAVE BEEN REDUCED TO 5 ELEMENTS: Ownership, Skills Development and Enterprise & Supplier Development have been made priority elements. There are sub-minimum targets based on certain weightings within these elements, and if a company does not meet these subminimum targets, they will be discounted a level. 3 Ownership is a compulsory priority element.

It is clear that the 2013 Codes are significantly stricter than the 2007 Codes. Herewith some of the main differences: • Entities have to comply with Ownership in the 2013 Codes, or face penalisation of one level. The 2007 Codes did not have priority elements, and therefore no penalisation.

• Under the 2007 codes it is possible for a QSE company to achieve a good level without even considering Ownership or Skills Development. But under the 2013 codes, both these elements are priority elements. QSE entities must be evaluated under all elements and do not have a choice anymore as in the 2007 Codes.

• 100% and 51% black owned4 EMEs and QSE entities automatically obtain a level 1 and 2 respectively.

• The threshold for the 2013 Codes is much higher than the original 2007 Codes. Therefore, a level 4 in the 2007 Codes will be a level 7 or 6 under the 2013 Codes.

• Entities have to be evaluated as an Empowering Supplier.

The details of this concept are very important, as this will determine whether your certificate will be accepted in the market or not.

• It is imperative that you purchase from at least 51% black owned or 31% black female owned businesses. To comply, the biggest challenge is to identify companies with these credentials that can form part of your supply chain.

• Companies have to develop not only 51% black owned business, but also 51% black owned suppliers.

• Large enterprises are measured using Economic Active Population figures for the different ‘black’ race groups in a measured category. Therefore, African males, African females, Coloured males, Coloured females, etc. are all evaluated separately.

Socio Economic Development

B -BBEE

These are only a few of the challenges, which will form part of the B-BBEE evaluation in future. Even though the amended Codes came into effect on 01 May 2015, the Dti issued Clarification note No. 38764 stating, among others, the following: (a) Confirm that the Amended Codes of Good Practice, gazette No 36928 will come into effect on the 1st May 2015.

Clarify that all B-BBEE verifications conducted using the financial year ending before 30 April 2015 can be verified using the old Codes of Good Practice, gazette No 29617 and all B-BBEE verifications conducted using the financial year ending after the 1st May 2015 must be verified using the Amended Codes of Good Practice, with the exception of the Sector Codes.

Therefore, companies with a measurement period (i.e. financial year-end) before 1 May 2015 can still be evaluated under the current Codes, Government gazette 29617, or their relevant Sector Codes. Please note that the following sector-specific codes have not been changed yet, and therefore these rules will still apply to industry entities until this has been amended: 1. Agricultural Sector Code; 2. Tourism Sector Code; 3. Transport Sector Code; 4. Construction Sector Code; 5. Property Sector Code; 6. Chartered Accountancy Sector Code; 7. Financial Sector Code; 8. Information and Communication Technology Sector Code; and 9. Forest Sector Code Entities within these industries are still bound by the rules contained within the respective Sector Codes.

THE WAY FORWARD The fact of the matter is that B-BBEE is here to stay, and it will affect your business in one way or another. There is a very small percentage of business in South Africa not actually influenced by this legislation. Therefore, it is not very easy or advisable to simply ‘ignore’ a legislation of this magnitude, especially since government now consumes 32% of national income each year. The effect is that a large part of the economy is connected to government and its business.

The best way forward is through planning, planning and planning. It is in your interest to engage with a reputable, experienced consultant (beware, there are numerous ‘fly by nights’ out there) and to do proper planning to situate your business correctly. B-BBEE can become a big competitive advantage, but it depends on the culture of the business. In plain English, if you want to do business in South Africa, B-BBEE is going to play an integral part.

There is still speculation among some about the ‘constitutional’ validity of the Amended Codes. Whilst I won’t enter into that debate, I can say with surety that it is effective, and will be implemented in due course. One cannot simply ignore it.

FRONTING There are some companies with huge success stories, but there are also some companies involved in fronting schemes.

48

Image by houstondwiPhotos mp Please note that the Broad-Based Black Economic Empowerment Amendment Act, 2013 (Act No. 46 of 2013) has criminalised fronting. A party found guilty of this offence can be subjected to: 1. A fine or imprisonment not exceeding 10 years, or both a fine and such imprisonment, or if the person convicted is not a natural person, a fine not exceeding 10% of its annual turnover; or 2. A fine or imprisonment for a period not exceeding 12 months, or to both a fine and such imprisonment.

The above depends on the party committing the offence.

CONCLUSION B-BBEE strategies will incur a cost to your business, but by structuring some of your initiatives correctly, this can undoubtedly be a cost advantage to the business. The information shared here is just a drop in the ocean; B-BBEE is becoming a more stringent policy enforced by government.

Do things the correct way, and be sure to obtain the correct advice from an expert in the field. If something does not sound correct, there is a good chance that it is not. Rather obtain a second opinion and comply in the correct manner.

NOTES: Please note that this has been substituted with the Broad-Based Black Economic Empowerment Amendment Act, 2013 (Act No. 46 of 2013) which came into operation on the date of publication of the proclamation, 24 October 2014.

Black refers to all African, Coloured, Indian and Chinese South African Citizens.

This depends on the size of the company.

Please note that the Ownership element needs to be evaluated.

GREEN BUILDING

Cape Town’s Black River Park named the first Green Star SA rated office precinct in the country Black River Park in Cape Town has become the first office precinct in South Africa to receive Green Building Council of South Africa (GBCSA) certified Green Star SA ratings for all its buildings.

T

50

he eight buildings at Black River Park office precinct in Observatory, offering a combined 75 000m2 of office space, have earned unparalleled green building credentials. Besides being the first full office park to have all buildings Green Star SA rated, it is also home to the first Green Star SA Existing Building Performance (EBP) certified building and the first buildings to receive a 6 Star Green Star SA Existing Building Performance rating.

He adds, “We would like to see more business parks following this leading example. All the buildings at Black River Park were certified using the EBP rating tool. The EBP tool means that South Africa’s many existing buildings in established office parks can now be retrofitted with green innovations and certified. This has huge potential for positive impacts to our environment, our businesses and our economy.” Nedbank Corporate Property Finance sponsored the EBP tool.

Brian Wilkinson, CEO of GBCSA, comments, “This is a major achievement, both for Black River Park and for GBCSA. Certifying all eight of Black River Park’s existing buildings is quite a feat, especially for a precinct of this size. It is an exciting example of outstanding sustainable innovation, and confirms the vision of its management team and their outstanding commitment to sustainability.”

Black River Park is home to more than 110 companies, including the GBCSA’s head office and South African Property Owners Association’s Western Cape offices. It is now owned by JSElisted Redefine Properties. Redefine acquired the landmark green office precinct as part of its Leaf Capital deal earlier this year.

JUNE 2015

GREEN BUILDING

Redefine CEO, Andrew Konig, comments, “The Black River Park complex has set itself apart with pioneering green initiatives and sustainable building management. We are exceptionally pleased to acquire this property, which perfectly supports our commitment to sustainability.”

The Black River Park buildings received maximum points on all credits targeted in their Green Star SA submissions. Three buildings received a 6-Star Green Star SA rating, three received 5-Star certifications and two earned 4-Star ratings.

Sally Misplon of Misplon Green Building Consulting, the Green Star Accredited Professional and principal participant in the green project team, guided Black River Park right from the very start in its certification project.

SOME OF THE GREEN INITIATIVES UNDERTAKEN BY THE OFFICE PRECINCT TO SECURE ITS RATINGS INCLUDE: • The largest roof-mounted photovoltaic system in Southern Africa.

• Feeding electricity back into the grid.

• A high-performance green cleaning programme.

• 68% of the tenants in the office park signed a Green Lease.

These leases encourage collaboration and govern the relationship between the building owner and the tenant to manage and operate the building along environmentally sustainable principles, to the benefit of both.

• For comfort and well-being, the building features performance glass and balcony overhangs, to reduce heat and shield against harsh sunlight.

• All lights in common areas were replaced with LEDs, with owners and tenants both benefiting from cost savings achieved as a result. A financing option was also offered to tenants to enable them to retrofit to LED in their own premises.

JUNE 2015

• Indoor air quality testing and management.

• All 6 Star rated buildings stood out for water and energy performance. They outperformed the Green Star benchmarks and achieved significant improvement on their baselines.

• Sustainable management and operations that optimise the buildings’ environmental performance.

• A green travel plan to encourage alternative modes of transport to and from work.

• Sustainable procurement and purchasing practices. For every product or consumable purchased by Black River Park, the most sustainable one is selected.

• All waste at the park is sorted into recyclable and nonrecyclable materials. It also correctly disposes of fluorescent tubing, batteries and e-waste. Garden waste is recycled and reused as mulch.

• Ecological gardens, including a vegetable garden and fruit orchard, are maintained with borehole water pumped on site.

Perhaps some of the most exciting green innovations at Black River Park are those involving the park’s tenants. These include holding a ‘cycle to work’ day, a clean-up of the Liesbeeck River that runs past the park and other activations with the precinct’s tenant community. Numerous other presentations and showcase tours are held for parties such as UCT, African Utility Week, Iziko museum and the like.

“It is wonderful to see an office park owner going above and beyond what’s required for certification,” says Wilkinson.

“These initiatives encourage people to do more within green spaces and enjoy their many benefits. They bring sustainable environments to life and encourage the wider community to become an active part of the green building movement.”
